Serial No. 231,734.

The invention relates to ice cutting machines-and more particularly to an ice cubing machine.

The invention has as one of its primary objects to provide a machine of the above character distinguished by its simplicity of construction and operation, which not only enhances its value both mechanically and commercially, but provides a design of a strong and durable nature.

' Heretofore in the manufacture of machines for cubing ice for table use, considerable inconvenience has been commonly experienced in the necessity of positively feeding the block of ice into engagement with the saws by hand which is not only a slow and tedious op ration, but is exceedingly dangerous to an? operator as Well.

However, according to my invention I have provided a machine wherein the block of ice is held substantially stationary and the saws for cutting the ice are moved relative to the block of-ice for cubing the same. An arrangement of this character offers the possibility of eliminating the hand operation heretofore pointed out, and makes available a commercially satisfactory machine which is completely automatic in operation and is capable of producing uniform cubes. Moreover inasmuch as the machine is completely automatic in operation and owing to the fact 7 that the ice is held stationary during the cubing operation, greatenproduction is realized with the minimum amount of labor.

Many of the advantages and much of the commercial value and acceptability of the invention are attributed to the novel construction of the machine, these advantages being obtained particularly because of the simplicity of the construction and the minimum number of parts employed. This enables the 'machine to be economically and quickly manufactured and easily assembled and renders the same strong and durable. The invention therefore depends for some of its advantages upon the specific details of construction illustrated and about to be described.

Other advantages and novel features of 0 construction which contribute materially to the mechanical efiiciency of the apparatus also add materially to its commercial value and acceptability and many of the foregoing I advantages, objects and structural features of the invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings.

Figure 8 is a detail perspective view illustrating the connection between the main frame and the sliding frame.

In general, the machine comprises a stationary main frame A and a sub-frame B mounted on the main frame and capable of horizontal and substantially vertical movements relative to the main frame. The subframe or saw carriage B is fashioned to support two sets of power driven saws C, D, and a single saw E. Each of the saws C lies in a substantially horizontal plane and is mounted upon a substantially vertically extending arbor F which operates, upon movement of the carriage in a horizontal direction, to cut the cake of ice. The saws D are disposed in vertical planes and are mounted upon the arbor G which as shown extends at 100 right angles to the arbor F and operates upon a movement of the carriage in a generally vertical plane to move the saws into engagement with the ice cake and to cut the same at right angles to the cuts formed by the saws C. The saw E, on the other hand, is carried by the arbor H journaled in suitable bearings formed upon the saw carriage to the rear of the arbor G and owing to the fact that saw E is arranged in. a plane at right angles to the planes of the saws D and spaced outwardly therefrom, it will be immediately apparent that this saw will perform the final out to sever the ice cubes from the cake of ice, the cubes falling into the chute I where they may be disposed of in any suitable manner.

In detail, the stationary frame A comprises a base 10 and a pair of standards 11 and 1'1 extending upwardly from the base and terminating in angularly offset portions 12 apertured to receive the upper ends of the angula-rly disposed guide rods 13 permanently secured to the base 10 as indicated at 14. Disposed upon the guide rods is a frame 15 having bearing portions 16 upon the upper and lower ends thereof slidably engaging the guide rods. The bearing portions 16 are formed with extensions 17 apertured to receive a pair of horizontally disposed bars 18. Thus it will be readily apparent that the frame 15 is capable of a substantially vertical sliding movement relative to the stationary frame A. The saw carriage B is mounted upon the frame 15 and is provided with bearing portions 19 slidably engaging the horizontal bars 18. Thus inasmuch as the saw carriage is mounted upon the upwardly movable frame 15 and is slidably arranged upon the horizontal bars 18 of this frame, it will be readily apparent that the carriage B is capable of horizontal and substantially vertical movements relative to the stationary frame A The saw carnage is provided with the vertically aligned bearings 20 (Fig. 2) within which the arbor F, carrying the horizontally disposed series of saws C, is journaled.

Extending at right angles to the arbor F is the arbor G journaled in bearings 21 formed in the carriage adjacent the lower end thereof and carrying the vertically disposed series of saws D. The arbor H carrying the saw E is journaled in bearings 22 formed in the lower bar 23 of the saw carriage, which as shown in Figs. 2 and 7 is in the form of a housing. The saw E, having a diameter substantially equal to the overall dimension of the series of saws D (see Figs. 3 and 5) is disposed below the series of saws and is arranged in a plane at right angles thereto, the arrangement being such that when the carriage B and frame 15 move upwardly upon the guides 13 as a unit the saws D will cut the ice cake at right angles to the cut formed by the saws C, and the saw E, owing to its position to the rear of the saws D, will subsequently engage the ice cake to cut the same at right angles to the cut formed by the saws.

For accurately guiding the carriage through the various movements heretofore pointed out, I provide the guide member 24 having integral bracket-securing portions 25, 26 and 27. Thebrackets 26 and 27, depending from the lower end of the guide member 24 (Fig. 2), are secured to the spaced upstanding projection 28 (Figs. 1 and 2) formed on the base 10, while the bracket 25 is secured to a projection 29 formed on the vertical upright 11 (Fig. 1). The guide member 24 in its secured position is disposed in aplane substantially parallel with the plane of the carriage B and is spaced a substantial distance therefrom. As shown in Figs. 2 and 3, the guide member 24 is preferably a' trape zium inshape and is composed of a substantially horizontal bar 30, a bar 31 extending upwardly from the bar 30 at right angles thereto and a tie bar 32 connecting the upper end of the bar 31 and the free end of the bar 30. The tie bar 32 has an upwardly extending portion 33 arranged parallel with the bar 31. Projecting inwardly from the saw carriage B is an ear 34 (Fig. 2) upon which an arm 35 is rigidly secured. As shown in Fig. 4, this arm projects laterally from the carriage and bridges the space between the latter and the guide member 24 and is provided at the outer end thereof with a roller 36 arranged to engage in a cam track 36 formed in the horizontal and upright bars 30 and 31 respectively.

Referring now to the specific means for driving the arbors F, G and H together with the means for moving the frame 15 and carriage B relative to the stationary frame A, a suitable prime mover is provided herein shown as an electric motor 38 (Figs. 1, 2 and 3) having a shaft 39 carrying a pair of sprocket wheels 40 and 41. The sprocket 40 is connected to the sprocket 42 upon the shaft 43 by means of chain 46 and the shaft 43 is connected through suitable reduction gearing, ence numeral 44, to the sprocket wheel 45. The sprocket wheel 45 is in turn connected to the idler sprockets 47 and 48 j ournaled upon the shafts 49 and 50 mounted upon opposite ends of the horizontal bar of the guide member 24, by means of a chain 51. As clearly shown in Figure 1, the chain 51 travels in the space provided between the guide member 24 and carriage and is rigidly secured to the arm 35 adjacent the free end thereof by means of a pin 52 (Fig. 4) extending through one of the links of the chain and journaled in the channel-shaped extension 52' of the arm 35. Thus the chain 51 is connected to the saw carriage B and inasmuch as the chain is designated generally by the referj mounted upon the stationary guide member 24, the saw carriage B will be compelled to follow the circuitous course of the chain. It will further be noted that the saw carriage will move in an accurate predetermined path during the scoring of the ice irrespective of the slack in the chain owing to the connection heretofore described between the carriage B and cam groove 36 formed in the guide member 24. In order that the slack in the chain may be compensated for, I provide an adjusting bracket 53 secured to the guide member 24 by means of the bolts 54, see Fig. 2. As shown, these bolts extend through suitable apertures formed in the bracket and through an elongated slot formed in the vertical portion 33 of the tie bar 32. A sprocket 56 is journaledupon one end of the bracket 53 and arranged to engage the chain 51. The arrangement is such that when it is desired to take up on the chain 51, the bolts 54 are loosened and the bracket together with the sprocket 56 is moved upwardly longitudinal-- ly of the slot. From Figs. 2 and 3, it will be clear that chain 51 has approximately the same trapezium shape as the frame 24.

For imparting a continuous drive to the arbors F, G and H throughout the several movements thereof, I provide a spline shaft 57 (Fig. 3) journaled in bearings 58 formed in the frame 15 at the lower end thereof. Positioned upon the spline shaft 57 adjacent one end thereof is a sprocket 58connected to a sprocket 59 (Figs. 1 and 2), carried by the swinging shaft 60, by means of a chain 61. Secured to the shaft 60 is a second sprocket 62 (Fig. 2) arranged in alignment with the driven sprocket 41 on the motor shaft 39 and connected thereto by means of the chain 63. For supporting the swinging shaft 60 and accordingly the sprockets 59 and 62 in spaced relation to the spline and motor shafts, I provide adjustable members 64 and 65. Mounted upon the ends of each of these members 9 are the forks 66, 67, 68 and 69. The fork 66,

upon one end of the member 64, is ournaled upon the spline shaft 57, as shown in Figure 2, while the fork 67 upon the opposite end of the member 64 together with the fork 68 and the upper end of the member constitute bearings for the shaft 60. The fork 69 is secured upon the lower end of the member 65 and journaled upon the motor shaft 39. The members 64 and 65 are each composed of two bars connected together by means of adjusting nuts 70 and 71 so that the length of the chains 61 and 63 may be readily adjusted when necessary. Thus from the foregoing, it will be readily apparent that .the members 64 and 65 together with the shaft 60 have a grasshopper motion which permits the spline shaft 57 to move upwardly with frame 15 and at the same time effectively drive the arbors.

For establishing a driving connection between the spline shaft and arbors F, G and H, I provide a gear 72 (Fig. 2) keyed to the bushing 73 slidably mounted upon the splines 74 of shaft 57 and carried by the lower end of the housing 75 formed integral with the saw carriage B. Meshing with the gear 72 is a second gear 76 (Figs. 2 and 7) keyed to the shaft 77 which is journaled in the extension 23 of the housing 75 and is provided at one end thereof with a beveled gear 78 meshing with a correspondingly beveled gear 79 keyed to the arbor H. Thus a positive drive connection between the spline shaft 57 and arbor H is effected irrespective of the movement of the spline shaft. Keyed to a stub shaft 80 (Fig. 2) journaled within the housing 75 is a gear 81 meshing with the gear 76 and with a gear 82 mounted upon one end of the arbor G for driving the same. Secured to the arbor G adjacent the gear 82 is a beveled gear 83 meshing with a beveled gear 84 keyed to the lower end of the arbor F. As shown in Figure 2 of the drawings, all of the gears and respective shafts for actuatin the arbors are disposed within the housing 5 of the carriage which is closed at the outer end thereof by means of the cover plate 85. Thus, in view of the fact that the driving means for the arbors as well as the arbors themselves are carried by the saw carriage, the saws will be positively rotated irrespective of the movements of the saw carriage B.

For supporting the block of ice in proper position with respect to the saws, I provide an abutment or support 86 (Figs. 3 and 5 rigidly secured to the saw carriage as indicated generally at 87 and accordingly movable therewith; As shown, this abutment member 86 comprises a substantially fiat por tion 89 and an upstanding portion 90 constituting a stop for the block of ice, limiting the inward movement of the ice. The member 86 is also provided with a second substantially flat portion 91 arranged in a plane substantially lower than the plane of the portion 89 and is connected thereto by means of the inclined portion 92 (Figs. 5 and 6). The portion 89 is provided with a series of saw slots 93 for receiving the saws D and the slots 94 for receiving the two lower saws of the series C. The portion 91 is provided with an aperture 94 through which the saw arbor H may project. Secured to the abutment member 86 immediately adjacent the slots 94 is a cover plate 95 (Figs. 3 and 5) cutaway as indicated at 96 for receiving the saw E, which as will be noted from Figure 5 of the drawings, lies flush with the surface of the cover plate. As shown in Fig. 6, the cover plate 95 is spaced from the abutment member 86 a distance exactly corresponding to the distance the saws C and D project through the slots, or in other words the saws O and D do not project above the surface of the cover plate. The lower end of the abutment member 86 is inclined with plate 95 until the respect to the horizontal, as indicated at 97 (Fig. 5), and the space between member 86 and the cover plate 95 is closed by flush riveting a strip 98 to member 86 and cover plate, forming the chute I for the ice cubes cut by the machine. With the foregoing arrangement, it will be apparent that during the cutting of the ice by saws C, the upstanding portion 90 will limit the depth of the cut. Moreover, by reason of the fact that the cover plate is spaced from the upstanding portion 90 a distance equal to the depth of the cuts made by the saws C and D, and inasmuch as the saw E lies substantially flush with the surface of the cover plate and follows the saws D during the upward movement of the saw carriage B and cover plateto sever the cubes from the block of ice, the portion of the ice block from which the cubes have been severed will be supported directly upon the cover saw E has completed its cut. The cubes, as they are severed from the ice block, will slide down the inclined portion 92 under the saw E and into the chute I, and so out of the machine. See Figs. 5, 6 and 3.

For supporting the ice block 99 in position to be operated on by the saws, I provide a platform 100 (Figs. 1 and 6) and an elevating platform 101 positioned adjacent to the platform 100 and having the forward end thereof normally engageable with the floor line so that the ice block may be readily positioned upon the platform 101 without lifting the same. After the block of ice is placed upon the platform 101 the latter may be elevated (by operating a Windlass 101 actuated by the crank 102) to substantially the same level as the platform 100, whereupon the ice is merelyslid off upon this latter platform against the supports 103 projecting upwardly from the sides of the platform 100.- Owing to the fact that the horizontal cutting of the ice is in the direction of the supports 103 the ice will be firmly held thereagainst.

To eliminate positively feeding the ice into position to be engaged by the saws, the platform together with the saw carriage and frame 15 are arranged at an angle to the horizontal, as clearly shown in the drawings, so

thatthe ice by reason of its own weight will automatically move into engagement with the saws C at the completion of each cut.

\Vhile it is believed that the operation of the machine will be thoroughly understood from the foregoing description, a brief outline thereof will be given. The block of ice is properly positioned upon the platform in the manner heretofore pointed out and the prime mover is started which drives the arbors F, G and H and at the same time through the chain 46 imparts rotation to the sprocket 45, which in turn drives the chain 51'. The latter, owing to its. connection to the saw carriageB, will move the saw carriage horizontally upon the guide bars 18 to a posit-ion where the series of saws C engage the block of ice and form the horizontal cut, which is shown completed in Figure 2. After this out has been completed, the saw carriage, to= gether with the support 87, frame 15 and accordingly its spline shaft 57 move upwardly as a unit to first engage the saws D with the block ofice to cut the same vertically and to subsequently engage the saw E with the ice to score the same at right angles to the cut aforesaid, whereupon uniform cubes are severed from the block of ice. The cover plate 95, as heretofore pointed out, immediately follows the saws and engages the portion of the block of ice from which the cubes have been cut to hold the same in position upon the platform 100 until the carriage returns for the second series of operations. After the saw carriage has completed the horizontal and vertical movements set forth above, the chain carries the saw carriage di agonally across the frame 24. During the diagonal travel of the carriage, the latter will move horizontally along the guide bars 18 and splines 74, while these members at the same time are being lowered upon the guides 13 toward their initial position. When the frame 15 has assumed its initial starting position the carriage will be located at the eX- treme left hand side of Figure 2. Figure 3 of the drawings clearly illustrates the position of the various parts during the return movement of the saw carriage.

, Thus from the foregoing, it will be readily apparent that the machine illustrated herein is completely automatic in the cubing operation and inasmuch as the block of ice is held substantially stationary during the scoring of the same, a greater production of ice cubes is realized with the minimum amount of labor.

Obviously, the present invention is not restricted to the particular embodiment thereof herein shown and described. Moreover, it is not indispensable that all the features of the invention be used conjointly, since they may be employed advanta eously in various combinations and sub-combinations.
